Hi All - I need some advice on a tank stand I have build and am about to put a 1 metric tonne tank on it .... So I have some trepidation here.
Basically I have taken a 196cm (6 foot three inches) wide wardrobe out of an alcove. On each end is a thick brick wall. On each wall I have bolted a reinforced steel plate, 5mm thick, which touches the concrete floor. Nine 8mm bolts are implanted through the plate into the wall with brass fittings ebbedded into the bricks. The plate has a top and bottom welded "lip" of 2x2cm solid steel. So the total top surface of each plate is 2.5 CM wide. The "lips" are supported by three hollow verticals of 2CM square steel tube. That's the plates described.
I plan to place three 7cm H bars, also called I Beam, from one side to the other WITHOUT A Centre support, spanning the 196cm gap on which I'll place plywood and a support for the glass box.
Now, 7cm I Beam is very VERY strong. My question is how many beams should span in order to support the weight without flexing at all ?
